Like all medicines, Cloxacillin Normon can cause side effects, although not everyone gets them:

• Hypersensitivity reactions:skin disorders, interstitial nephritis (kidney inflammation).

Cloxacillin sodium should not be used in solutions containing protein hydrolysates, lipid suspensions, amino acids, blood, or serum. It is compatible with most commonly used intravenous solutions (physiological serum or glucose).

The mixture of cloxacillin and aminoglycosides can cause substantial mutual inactivation, so they should not be mixed in the same container for administration.
